Poltys laciniosus

Fact Box Species: Poltys laciniosus (Helen Smith) Family: Araneidae formerly Argiopidae Body length: female: 9 mm male: 2 mm Habitat: On bark or dead twigs Toxicity: Uncertain; not an aggressive spider

Bands on legs Immature Well camouflaged

The most obvious physical characteristic of this species is the way it adopts an upright posture with the long, finger-like top of its abdomen pointing vertically. Its camouflage colours make it very difficult to see when it is resting on a bark surface. On the other hand, it has distinctive yellow-orange bands on the insides of its legs which can only be seen when the legs are extended. Please not that some other Poltys species are very similar in appearance so identification to species is probably impossible for anyone who is not an expert arachnologist.

This species makes a fawn/grey egg sac which is attached to a dead twig.

Spider(s) with a very similar appearance: Poltys illepidus.
